First ever “QSO” with ISS from Earth by Light “transmitter” on THz freq’s.
For the 1st time the San Antonio & Austin Astronomical Associations were able to successfully contact an inhabited object in space and have that contact confirmed photographically via astronauts onboard the ISS!! The video is of the actual flash project which involved the use of two 800 Millon Lumen spot lights and a 1 watt blue laser along with numerous participants with handheld spot lights!
